The several inlet;

,wardly andoutwardly-extending deflectorwings or flanges 19, said wings .or flanges 19, extending substantially flush with the ends of said openings or slots 14, and the plates 18, being secured to thehead or cap 4, by means The ends of the angular projecting portions or corners 13*, of the triangular-shaped end13, of the'inletpipe 9, abut against the'plates 18, leaving the slots 12, intermediate said plates andcorresponding in depth to the thickness of said lates. As a means of modifying the pitc produced at the several municating with the respective fluid-pressure pipes, said wings or flanges 19, maybe bent inwardly and above-said inlet-o enings or slots 14, at an acute angle until t e desired pitch is secured. As a further means 'of Y modifying the pitch, above referred to a deflector-lip or plate 21 maybe mounted and interposed between t e wings or flanges 19, and atthe rear of said'inlet-openings or slots 14, (see Figs. I and IV), the base portion 22,

' thereof, being slidably and adjustablypitch of tone arising in-the several fiuid pressure pipes, and, more particularly, by

mounted upon the inlet-pipe 9, by means of a screw 23, assing through a slot 24. If desired, the efiector-wings or flanges 19, and deflector-1i s 21, ma be made integral-with the inlet-pipe 9; an the wings 19, and'de-.

flector-lips 21, interposed between said wings",

might also be made integral with each other.

As the operating-fluid passes through the inlet-pipe 9 .it impinges against the cap or head 4, an is directed outwardly through the slots or recesses 12, and over and against the lips or tongue-pieces 15, of-the inletopenlngs or slots 14, communicating with the several fluid-pressure pipes 10, and thereby sounding the horn in a well known manner. As a further. means of securing the desired which their relative pitches ma be made such as'to produce a chordor ch1me, when sounded together, a valve is mounted in each of the longitudinally-extending sectors, ref-- erably near the frontor discharge ends t ereof, said valve consisting of a base portion 25, and a depending vibratingplate 26, adapted to vibrate crosswise inthe pipe in which it is mounted, said base portion .325," being slidably-secured to the innerside-of the convex face 2, by means of an 'jYadj-u'sting-nut 27,

passing through said I'face Q; and through a slot 28. The depending-plate 26, may be of any suitable and convenient-"form and by positioning the several valves in the severali fluid pressure pipes, atdiii'ereritrelative positions a perfectchord or"chime may 6 roduced.

he improved means for operating the horn, consists of an exhaust-pipe 29, leading from the motor, and provided with a T-pipefitting 30, provided witha cylindricahshaped valve-body or housing 31.

A reduced lateral ing-pipe 33, leading shed and whereby to regulate the pipe or boss 32, leads from thevalve body 31, and is connected to the inlet-pipe 9, ot the horn by means of' a connecting-pipe 33. The ends-of'thecylindrical valve-b0 y 31, are closed by means of disk bearing-plates or heads 34, provided with central bearin openings carrying the ends of a rotatably; mounted valve-bearing-shaft 3 5. The valve, proper, consists 'of an arm 36, terminating at one end in a hub or bearing head 36", se-. curedto'the shaft 35, by means of a screw 3'1 and at the other in a concavo-convex-shapled disk-bearing-head 38, conforming to. the adiacent inner clylindrical wall ofthe'valvebody 31, said ead 38, normally closing the lateral inlet opening 32", and being of suificient size to. close the main outlet-openw ing 29, of the exhaust-pipe 29, when 9 erated by the means heremafter descrl ed;

One end of the shaft 35, is intersected means of an operating-armor lever 39, .a

justably-mounted therein by means of a setscrew 40, and the free end of said lever 39, is provided with a spring 41, normally closthe inlet-opening 32, as shown in Fig. and is provided with a cable 42, designed to operate against the resistance of said spring, said cable being connected to afootlever, or other suitable and convenient 0 era'ting-device (not shown), by means of w ich the valve, proper, may bemoved or partially close the outlet opening 29, and

to correspondingly open the inlet-opening- 32, whereby more or less of the operatingfluid may be diverted through the connectto inlet-pipe 9, of the tter is operated as dequantity horn whereby the and pressure of th'e operating-fluid.

As a means of providing against an oversupply or pressure of operating-fluid inthe in et-pipe 9, whereby too high a pitch of tone would be produced, an escape-valve is formed at the side of said inlet pipe' 9, corn sisting of'a vent-o by a disk-valvelower end of a vertically-arrangedmovable bar or pin 45, having its up er end passing througha guide-opening of th a guide-bracket or housing 46, the ase ends of-which are mounted on the inlet pi e 9, by means of screws 47. A spring 48, tal ies over ening 43, normally closed the pin 45, and under the upper end of the guide-bracket, whereby to normally close the vent-opening Y 43, the pressure of the valve-plate being?regu1ated by means of an adjusting-nut 49, threaded upon the lower end' ofthe pin 45.

From the foregoing description, taken in connection with the' accompanying drawings, the operation and advantages of my invention will be readily understood.
